How much power can 650cc injectors handle?
So 650cc injector= 650hp if injector is running at 100% duty cycle. I would scale it down a bit to around 80-85% duty, so that would put you at around 520-550hp range. A single walbro can flow enough fuel to feed the car about 500-550hp, but I would advise against it.
